SFECEFICATION forming part of Letters Patent No. 342,082, dated May 18,1886.

Application filed Fcbruary15,1886. Serial No. 191,968.

.To @ZZ whom it may concern.-

Be it known that I, EDWARD FALEs, a citizen of the United States,residing at St. Louis, in the county of St. Louis and State of Missouri,have invented certain new and useful Improvements in Devices for FeedingFurnaces with Fuel, of which Vthe following is a specification,reference being had therein to the accompanying drawings.

My invention relates to improvements indevices for feeding fuel tofurnaces.

The object of my invention is to feed the fuel in uniform quantities toall parts of the furnace in such a manner that cold drafts of air willnot be admitted to the furnace above the fuel or body of the fire.

In the ordinary methods of feeding fuel to furnaces the doors are openedand the fuel thrown in through the open doors. As a natural consequence,cold drafts of air are admitted, which not only check the intensity ofthe iiame, but chill the furnace, and in steamboiler furnaces the steamruns dow n, and the sudden contractions and expansions` of the ilues,dto., incident to these sudden changes do great injury to the boiler.Besides, a' vast amount of heat is wasted in bringing the furnace to thesame degree of temperature it was in before the doors were opened.

In the drawings, Figure 1 is a longitudinal sectional view of my feedingdevice as applied to a brick-kiln. Fig. 2 is a'front view of thefurnace'door with the charger inserted. 3 is a rear view of thefurnace-door with the charger inserted. Fig. 4 is a view inperspectiveof one form of charger. Fig. 5 is a side elevation, partly insection, of a steamboiler in which the charger is a modification of theone shown in Fig. `5.' Fig. 6 is a front view of the steam-boiler andfurnace shown in G. Fig. 7 is a side view of a cylindricalcharger havinga door in one side thereof. Fig. 8 is a plan or top view of the devicesshown in Fig. 8.

A indicates the furnace or combustionchamber, which may be of anydesired form or structure, and B indicates the grate, which also may beof any devised form; but I prefer to y use the fire-pot grate shown inthe drawings, for the reason that better results can be obtained fromthe use of it and a more perfeet combustion insured.

'Ihe fire-pot or grate B forms the subjectmatter of an application filedby me December 22, 1885, Serial No. 186,454., and need not be furtherdescribed or referred to in this application.

Gis the door, which is hinged to or secured to a suitable cast-ironframe, D, as shown in Fig. 2, in which is located the tube or sleeve E,through which the charger F is inserted to feed the fuel to the furnace.

The tube or sleeve E is placed in the door O, so that it can be readilyturned around, and is provided with a hinged door, G, which falls andcloses the inner end of the tube or sleeve E when the charger F isremoved after having deposited its charge of fuel on the fire. The tubeor sleeve E is also provided with a smaller or supplemental valve ordoor, H, which drops into the charger when the same is being removedfrom the furnace, and prevents the ingress of air into the furnace.

The charger F is made Vshapcd in crosssection and adapted to twithin acorresponding recess in the tube or sleeve, so that when the charger isfilled with fuel and pushed into the sleeve E the valved doors G and Hwill be raised, as shown in Fig. 1, and the charger pushed into thefurnace as far as desired. After the charger has been pushed into thefurnace as far as is necessary it is turned over, together with the tubeor sleeve E, and after the charge of fuel has been deposited on thegrate-bars or fire the charger and sleeve are turned into their originalposition and the charger drawn out of the sleeve or tube. The charger,after being inserted th rough the sleeve or tube into thecombustionchamber, may be tilted first to the right and-then to theleft, so as to throw the fuel to the sides of the furnace, or, if turneddirectly over, the fuel will be deposited near the center of the fire.

It may be proper to remark in this connecA tion that the rear end of thecharger' is solid or closed to the top, as shown at I, so that thecombustion-chamber will have no connection with the external air whenthe charger is inserted through the tube or sleeve E, and it will benoticed that when the charger has deposited its load and been turnedback to the position shown in Fig. 1 and on being withdrawn from thetube or sleeve E, the4 door or valve H will drop into the cavity of theIOO charger, and thus prevent the air from the outside from rushing intothe furnace above the grate, and as soon as the charger has beenWithdrawn the valve G will drop and close the inner end of the tube orsleeve E, and thus -effectually prevent the entrance of external ,bywhich the operator can readily manipulate the charger whether it isfilled with fuel or not.

In Figs. 5, -6, 7, and 8 I have shown amodification of my fuel-charger,and in this case the tube or sleeve E does not revolve, but is pivoted,as shown at M N, and adapted to be turned to the right or left on thesepivots, so

that the fuel can be deposited to one side or the other of the furnace.In this instance, also, the charger F is adapted to be turned in thetube or sleeve E so as to deposit the fuel through the door or opening Oon the re in the furnace, and in this instance the inner end of thelcharger is closed, so that the outside air cannot rush into thecombustion-chamber.

As before intimated, the charger shown in Figs. V5, 6,. 7, and 8is'providcd with a door, O, which is raised or opened when the chargeris being filled, but closed before the charger is pushed intothecombustionchamber, andwhen said charger is pushed into thecombustionchamber over the fire it is turned into the position shown indotted lines inFig. 5,whenthe door will open and allow the fuel to bedeposited onto the fire, after which the charger is turned so the doorOwill close when it is drawn back and in position to he refilled withfuel. The charger shown in Fig. 5 is adapted to be withd rawn from thetube or sleeve E, a d oor or valve, I?, being hinged above the tube E,so

4 as to close kthe same when the charger is re-v moved therefrom. Thecharger shown in Figs. 7 and 8l is not adapted to be removed from thesleeve E, but is provided with a cap, R, which closes the opening in thesleeve or-tube E when the charger is drawn back.

The charger F, just described,and as shown in Figs. 5, 6, and 7, isprovided with handles S, so it can be readily turned by the operatorafter it has been pushed into the combustion-chamber, and the rear endof said charger is supported by a prop, T, which relieves the tube orsleeve of all strain while the charger is being filled with fuel.

V are peep-holes located in the upper portion of the casing D,and areclosed with mica or other suitable material.

WV are poke-holes located in the lower portion of the casing D, saidholes being closed on the inside of the casing by the pivoted valves ordoors A, said valves being composed of a heavy casting having the sidenext the casing perfectly straight, so as to fit closely against theinside of the said casing. These valves or doors are arranged to openinward toward the fire when the poker is inserted, but will return againto their normal position and close the openings WV when the poker isremoved.

Having thus described my inventiomwhat I claim, and desire to secure byLetters Patent, 1s-
